When Google announced its new Movies service today, some of the details of the service's launch were omitted in the information overload that is I/O. But now that we've had a minute to regain our composure and, you know, investigate, we've got some exciting news about Google Movies: you can start renting and watching right now (note: only the United States is currently supported):

The catch is that you'll only be able to do it from your personal computer (via the Web Market or YouTube in the browser) or on a Motorola XOOM in the Videos app for the moment (we're assuming that means it's limited to Honeycomb Android devices for the time being). Given that Google plans to update Google TV devices to Android Honeycomb 3.1, Revue owners should be rejoicing.

Also, the YouTube version gives you Rotten Tomatoes review scores, cast info, and lets you use your Google account with Google Checkout to buy straight from your browser.
